SIGNAL.

Application filed February 26, 1919.

To all whom it may concern:

Be it known that I, JAMns S. BAKER, a citizen of the United States, and a resident of Texarkana, in the county of Bowie and State of Texas, have invented new and useful Improvements in Signals, of which the following is a specification.

This invention relates to signals and has particular reference to that class of signals used in connection with the exhaust pipe of an automobile engine.

An important object of the invention is to provide in a device of the above mentioned character a means whereby the various cooperating elements thereof may be so positioned with respect to each other as to cause the exhaust gases to produce a signaling noise when escaping into the atmosphere.

A further object of the invention is to provide in a device of the above mentioned character a means whereby various cooperating elements thereof may be moved to such a position with respect to each other as to permit the exhaust gases to be passed through the device without being brought into contact with the sound producing elements.

A further object of the invention is to provide in a device of the above mentioned character a means whereby the exact position of various cooperating elements with respect to other cooperating elements may be readily determined.

A further object of the invention is to pro vide a means whereby numerical indicating combinations may be employedto indicate the position of various cooperating elements with respect to each other.

A further object of the invention is to provide in a device of the above mentioned char acter a means whereby a given numerical combination may be changed to that of other desired numerical combinations.

Other objects and advantages of the invention will be apparent during the course of the following description taken in connection with the accompanying drawings.

In the drawings, forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Specification of Letters Patent.

Fig. 9 is a diagrammatic View showing the passage of the exhaust through one of a plurality of sound producing elements.

In the drawings, wherein for the purpose of illustration is shown a preferred form of my invention, the numeral 10 indicates a pipe having openings 11 arranged therein, the pipe 10 being preferably formed solid intermediate the openings 11 as shown at 12. Upon the pipe 10 substantially intermediate the openings 11 there is secured an intermediate section 13 which is provided with a bypass lt and arcuate-shaped groove 15 extending substantially throughout the circumference of the section as clearly shown in Fig. 6. The section 13 is provided diametrically opposite the bypass 14 with a duct 16 having a port 17 opening into the atmosphere as clearly shown in Figs. 2 and 3. Vi ithin the duct 16 at each end thereof there is suitably arranged whistles 18 and 19, which whistles are held in a desired position by means of bushings 20 and 21. These bushings are retained in position by means of disks 22 and 23 which are rotatably mounted upon the solid portion of the pipe 10 and free to rotate with respect to the intermediate section 13. The disk 22 is provided with a groove 2& adapted to receive a flange 25 carried at the end of the intermediate section 13. The disk 22 is provided with a plurality of lugs 26 adapted to enter corresponding notches 27 arranged within a head 28, which head is rotatably mounted upon the pipe 10 and locked against longitudinal movement by means of nuts 29. In order to support that end of the head 28 contacting with the disk 22 there is provided a flange 30 engaging the inner surface of the end of the l cad 28 as clearly shown in Figs. 2 and 3. In order to ali ord a connnunication between the bypass 1 t and the interior of the head 28 there is provided an opening 31 adapted for registration with the bypass 1t and a similar opening 32 provided by the disk The disk 23 is provided with an arcuate-shapegroove similar to that provided by the intermediate section and indicated by the numeral 15. The disk 23 like the disk is provided with an annular groove 3 1 adapted for the reception of a flange provided by the intermediate section 13. T he disks 22 and 23 are both provided at their peripheral edges with gears 36 and 37 respectively and are adapted to mesh with a gear 38 carried by a manually rotatable stem 39, the end of which is adapted to enter apertures a0 and 4:1, the apertures 10 being arranged in proximity to the gear 36 and the apertures n being arranged in proximity to the gear 37. The disk like the disk 22 is provided with a plurality of lugs t2 arranged within notches 4.3 carried by a head rst similar to that indicated by the numeral 28. The head d-i is rotatably mounted upon the pipe 10 and locked against longitudinal movement by means of lock nuts 15. In order to support that end of the head as within which the lugs 42 are arranged there is provided a flange 46 car ried by the disk 23, the flange 46 having engagement with the inner surface of the head 14: as clearly shown in Figs. 2 and 3. Upon the heads 28 and 1st bands 47 and +18 respectively are ar'anged. These bands are provided with numerals as clearly shown in Fig. 1 and are retained in position by means of bolts 19 passed through the ends thereof. Upon the intermediate section 13 there ar ranged a band 50 which is provided with numerals corresponding to the numerals carried by the bands 4:7 and as. The band 50 is secured in position by means of a bolt 51 passed through the ends thereof as clearly shown in Fig. 1. By means of a union the pipe 10 is secured to the exhaust pipe leading from an internal combustion engine, not shown, and by means of a similar union the pipe 10 is secured to the exhaust pipe 55 leading to a mufiler, not shown, if it is desired in any instance to employ-a inui'lier.

In use, the various cooperating elements of the device normally retain their positions with respect to each other as shown in Fig. 2, thereby permitting the exhaust gases to pass through the device in the directions of the arrows thereon without cou'iing into contact with the whistles 18 and 19 or other noise producing elements.

It will be noted that the numerals 12 carried by bands 4'7 and 4L8 register with the numerals 12 carried by the bands 50 when the various cooperating elements are in the position shown in Fig. 2.

lVhen it is desired to move the various co operating elements to such a position as will cause the whistles 18 and 21 or other noise producing elements to be actuated upon by the exhaust gases, the end of the spindle 39 is placed in one of the apertures 10 and rotated, in which instance the gear 38 engaging with the gear will cause the disk 22 to be moved to such a position as will sever communication between the bypass 1% and the interior of the head lVhen this communication has been severed, connmmication between the interior of the head 28 and the groove 15 is established through the opening 31. When communication is thus established the exhaust gases will be permitted to pass into contact with the whistle 18 or other noise producing element as indicated by the arrows of Fig. 3. By placing the end of the spindle 39 in one of the apertures ll the gear 38 by rotating the spindle 39 may be made to move the disk 23 into the position diagrammatically shown in Fig. 9, in which instance communication between the head at and the bypass 14 is severed and tne exhaust gases, assuming that communication between bypass 1st and the interior of the head 28 is established, will pass out of the head 28, into the groove 33 whereupon they are directed into contact with the whistle 19 or other noise producing element in the direction of the arrows shown in the diagran'miatic illustration of Fig. 9.

By employing the adjustable bands &7. 4:8 and 50 it is apparent that a given combination which indicates the position of the elements as shown in Fig. 2 may be changed to various combinations, therefore. it a given combination should be generally known it would be necessary only to remove either of the bolts as or 51 and make a suitable adjustment of the bands to establish a new combination which would indicate the position of the elements as shown in Fig. 2.

It is to be understood that the form of my invention herewith shown and d escribcd is to be taken as a preterred example of the same, and the various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
